What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Pioneer Tangential Tracking
The most accurate way of playing a record is with a tone arm that remains always tangent to the record groove, since this is how the groove was cut. Only a tangential tracking arm can do this.
A tangential tracking arm, when properly designed, engineered and manufactured, eliminates skating force and lateral tracking error, along with the excessive, often irregular record wear they cause. At Pioneer, we have successfully devolped just such a tangential tone arm. It uses a non-contact linear motor for smooth, vibration-free, lateral movement.
 Compare the Pioneer tangential-tracking tone arm to competing versions. Others depend on vibration-prone motors driving rollers, worm screws or pulleys. In terms of performance, there's simply no comparison.
Four advantages of tangential-tracking tone arms
1 - Lateral tracking error, for all practical purposes, remains zero throughout play. Thus, intermodulation distortion is avoided.
2 - There is no inward skating force, making an anti-skating system unnecessary.
3 - Lateral balnced  is ideal
4 - The arm can be short, thus reducing effective mass.
Tangential Tracking:  for reduced tracking error and better defined sound
Non-contact linear motor for arm movement:  for high signal-to-noise ratio and smooth arm tracking
Rigid, short low-mass straiht PG tone arm:  tarnes resonance for better tracking.
Coreless DC direct0drive motor with Stable Hanging Rotor:  provides smooth rotation and perfect stability.
Quartz-PLL servo plus Periphery Integration:  rock-steady platter-speed accuracy with and load.
Computer-controlled fully automatic operation:  fully protects arm and motor from improper operation
Universal cartridge connector:  any standard cartridge of your choice can be used.
